All Implemented Interfaces:

PreRenderable, Renderable

public class ColladaController
extends Object
implements Renderable, PreRenderable

Executes the mapping from COLLADA to World Wind. Traverses a parsed COLLADA document and creates the appropriate World Wind object to represent the COLLADA model.

Field Detail

colladaRoot

protected ColladaRoot colladaRoot

Collada document rendered by this controller.

tc

protected ColladaTraversalContext tc

Traversal context used to render the document.

Constructor Detail

ColladaController

public ColladaController(ColladaRoot root)

Create a new controller to render a COLLADA document.

Parameters:

root - Parsed COLLADA document to render.

Method Detail

getColladaRoot

public ColladaRoot getColladaRoot()

Indicates the COLLADA document that this controller will render.

Returns:

The COLLADA document referenced by this controller.

getTraversalContext

public ColladaTraversalContext getTraversalContext()

Indicates the traversal context used to render the COLLADA document.

Returns:

The active traversal context.

initializeTraversalContext

protected void initializeTraversalContext(ColladaTraversalContext tc)

Initializes this COLLADA controller's traversal context to its default state. A COLLADA traversal context must be initialized prior to use during preRendering or rendering, to ensure that state from the previous pass does not affect the current pass.

Parameters:

tc - the COLLADA traversal context to initialize.

preRender

public void preRender(DrawContext dc)

Specified by:

preRender in interface PreRenderable

render

public void render(DrawContext dc)

Causes this Renderable to render itself using the provided draw context.

Specified by:

render in interface Renderable

Parameters:

dc - the DrawContext to be used

setColladaRoot

public void setColladaRoot(ColladaRoot colladaRoot)

Specifies the COLLADA document that this controller will render.

Parameters:

colladaRoot - New COLLADA document to render.

setTraversalContext

public void setTraversalContext(ColladaTraversalContext tc)

Specifies a traversal context to use while rendering the COLLADA document.

Parameters:

tc - New traversal context.
